Description
The TSV991/2/4 family of single, dual and quad
operational amplifiers offers low voltage operation
and rail-to-rail input and output.
These devices feature an excellent speed/power
consumption ratio, offering a 20 MHz gain-
bandwidth, stable for gains above 3 (100 pF
capacitive load), while consuming only 1.1 mA
maximum at 5 V. They also feature an ultra-low
input bias current.
These characteristics make the TSV991/2/4
family ideal for sensor interfaces, battery-supplied
and portable applications, as well as active
filtering.

This model is a trade-off between accuracy and complexity (that is, time simulation) of the TSV99x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements ...
